在工作中遇到过很多Sql server的数据需要导入到Oracle的,Sqlserver原本是自带导入Oracle的配置管理工具的(具体可百度sqlserver导入Oracle,有很多文档),但是由于效率问题被很多人遗弃了,这里介绍一个将Sqlserver的查询结果生成insert语句的方法,见下文。
1、编写sql server生成insert 语句的存储过程:
USE [SHMAP] GO /****** Object: StoredProcedure [dbo].[proc_insert] Script Date: 2016/4/13 15:33:41 ******/ SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO ALTER proc [dbo].[proc_insert] (@tablename varchar(256)) as begin set nocount on declare @sqlstr varchar(8000) declare @sqlstr1 varchar(8000) declare @sqlstr2 varchar(8000) select @sqlstr='select ''insert into '+@tablename select @sqlstr1='' select @sqlstr2=' (' select @sqlstr1= ' values ( ''+' select @sqlstr1=@sqlstr1+col+'+'',''+' ,@sqlstr2=@sqlstr2+name +',' from (select case -- when a.xtype =173 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar('+convert(varchar(4),a.length*2+2)+'),'+a.name +')'+' end' when a.xtype =127 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(20),'+a.name +')'+' end' when a.xtype =104 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(1),'+a.name +')'+' end' when a.xtype =175 then 'case when '+a.name+' is null then ''NULL'' else '+'''''''''+'+'replace('+a.name+','''''''','''''''''''')' + '+'''''''''+' end' when a.xtype =61 then 'case when '+a.name+' is null then ''NULL'' else '+'''''''''+'+'convert(varchar(23),'+a.name +',121)'+ '+'''''''''+' end' when a.xtype =106 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar('+convert(varchar(4),a.xprec+2)+'),'+a.name +')'+' end' when a.xtype =62 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(23),'+a.name +',2)'+' end' when a.xtype =56 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(11),'+a.name +')'+' end' when a.xtype =60 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(22),'+a.name +')'+' end' when a.xtype =239 then 'case when '+a.name+' is null then ''NULL'' else '+'''''''''+'+'replace('+a.name+','''''''','''''''''''')' + '+'''''''''+' end' when a.xtype =108 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar('+convert(varchar(4),a.xprec+2)+'),'+a.name +')'+' end' when a.xtype =231 then 'case when '+a.name+' is null then ''NULL'' else '+'''''''''+'+'replace('+a.name+','''''''','''''''''''')' + '+'''''''''+' end' when a.xtype =59 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(23),'+a.name +',2)'+' end' when a.xtype =58 then 'case when '+a.name+' is null then ''NULL'' else '+'''''''''+'+'convert(varchar(23),'+a.name +',121)'+ '+'''''''''+' end' when a.xtype =52 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(12),'+a.name +')'+' end' when a.xtype =122 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(22),'+a.name +')'+' end' when a.xtype =48 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar(6),'+a.name +')'+' end' -- when a.xtype =165 then 'case when '+a.name+' is null then ''NULL'' else '+'convert(varchar('+convert(varchar(4),a.length*2+2)+'),'+a.name +')'+' end' when a.xtype =167 then 'case when '+a.name+' is null then ''NULL'' else '+'''''''''+'+'replace('+a.name+','''''''','''''''''''')' + '+'''''''''+' end' else '''NULL''' end as col,a.colid,a.name from syscolumns a where a.id = object_id(@tablename) and a.xtype <>189 and a.xtype <>34 and a.xtype <>35 and a.xtype <>36 )t order by colid select @sqlstr=@sqlstr+left(@sqlstr2,len(@sqlstr2)-1)+') '+left(@sqlstr1,len(@sqlstr1)-3)+');'' from '+@tablename -- print @sqlstr exec( @sqlstr) set nocount off end
2、执行存储过程获取insert语句:
exec proc_insert 'SUP_UNIT';
3 、得出insert语句如下:
insert into SUP_UNIT (ID,NAME,PARENTID,ABBREVIATION,STATUS,ADDRESS,ZIP,TELEPHONE) values ( 1,'巴士集团',NULL,'巴士集团','0','','',''); insert into SUP_UNIT (ID,NAME,PARENTID,ABBREVIATION,STATUS,ADDRESS,ZIP,TELEPHONE) values ( 2,'浦东公交',NULL,'浦东公交','0','','',''); insert into SUP_UNIT (ID,NAME,PARENTID,ABBREVIATION,STATUS,ADDRESS,ZIP,TELEPHONE) values ( 3,'上海巴士电车有限公司',1,'巴士电车','0','卢湾区淮海中路398号','200093','65660600'); insert into SUP_UNIT (ID,NAME,PARENTID,ABBREVIATION,STATUS,ADDRESS,ZIP,TELEPHONE) values ( 4,'上海巴士二汽公共交通有限公司',1,'巴士二汽','0','东诸安浜路231号505室-H室','200050','64925849');
PS:如果insert数据量较大可以全复制然后保存在sql文件中,使用SQLPLUS命令执行sql脚本。
